[ros-users] rosmake CMakeLists.txt rosversion test

[Ken Conley]

FYI: last Monday, I upgraded (on trunk) the rosversion tool to take in
any stack name as an argument. It currently scrapes from the
CMakeLists.txt file, but as ticket #3010 progresses, I'll update it in
kind. We hope to have better version mechanisms for Diamondback.
